THW-2-LS / THHW-2-LS Stranded Copper Power Cable Abstract​ The THW-2-LS / THHW-2-LS Stranded Copper Power Cable, available in 14, 12, 10, 8, 6, 4 AWG with 19 strands, is a high-performance solution engineered for heating systems, featuring PVC insulation and a 600V rated voltage. Compliant with THW-2-LS and THHW-2-LS standards, it excels in both dry, damp, and wet environments, making it versatile for diverse heating applications.​ The 19-strand copper conductor enhances flexibility, enabling easy routing through tight spaces around boilers, furnaces, and underfloor heating setups. This design minimizes breakage risks during installation, ensuring long-term reliability. PVC insulation provides robust resistance to heat, moisture, and abrasion, safeguarding the conductor against harsh conditions in heating systems.​ With a range of AWG sizes, the cable adapts to varying power demands: smaller 14-10 AWG for residential heating components like thermostats and small boilers, while 8-4 AWG suit commercial/industrial systems with higher loads. Its 600V rating ensures compatibility with standard heating voltages, delivering stable power transmission.​ Compliant with industry regulations, this cable combines durability, flexibility, and safety, making it a trusted choice for efficient electrical connections in heating systems across residential, commercial, and industrial settings.
